And Oxidative Stress

Diabetes mellitus is one of the serious global health problems affecting a significant proportion of both developed and developing countries. Overproduction of free radicals and oxidative stress has been associated with the development of diabetic complications. In the present study, the antioxidant effects of metformin (MET), glibenclamide (GLI), and repaglinide (REP) were evaluated in alloxan-induced diabetic rats. The findings from this study may possibly help in understanding the efficacy of these standard drugs in managing the complications arising from diabetes mellitus (DM). Alloxan (130 mg/kg BW) was administered as a single dose to induce diabetes. Four (4) groups of rats (n=6) were used; group 1 served as diabetic control while groups 2, 3, and 4 were the diabetic test groups that received MET (25 mg/kg), GLI (2.5 mg/kg), and REP (0.5 mg/kg), respectively. The result of the study showed significant (p<0.05) improvement in the altered antioxidant enzymes (SOD, CAT) and GSH concentration in diabetic treated rats compared with the diabetic control group. MET and REP produced significant effect on the MDA concentration while GLI showed insignificant reduction in the MDA concentration compared with the diabetic control. Findings from this study suggest that the administration of MET, GLI, and REP exerts significant antioxidant effects in alloxan-induced diabetic rats, thus contributing to the protective effect against oxidative stress-induced damage during diabetic complications.

Several conditions such as chemotherapy and toxins can interfere with spermatogenesis and reduce sperm quality and production. In the case where natural antioxidant response cannot manage oxidative stress and free radical overload, oxidative damage occurs and this begins the genesis of many diseases of which diabetes is one of them. This has awakened the interest of researchers to the use of an alternative source of medicine and herbal medicine. Medicinal use of Curcuma longa dates back to ancient China and India; its constituents are stated to have anti-hepatotoxic, anti-inflammatory, stimulant, and antioxidant and used since ancient time as medicinal and nutritive origins knowing to possess androgenic activities and have well effect in diseases treatment in more countries world-wide. As an antioxidant Curcuma longa possible has a useful effect on spermatogenesis and sperm parameters. Wistar male rats (n=24) were allocated into six groups, positive control (n=4), diabetic control (n=4) and experimental groups (n=20), that subdivided into groups of 4 that received treatment of Curcuma longa rhizome powder with or without STZ-induced diabetes in the dosages (25 and 100mg/kg/day) for 21 consecutive days. In twenty-second day, the testes were removed and semen was collected from epididymis and prepared for analysis. The percentage of sperm viability and motility in the treatment groups increased mildly with a significance of: (p<0.05) in comparison to control group and with the diabetic group being critically lower than those in control group. This suggested that Curcuma longa may be promising in enhancing sperm health parameters.Keywords: Turmeric, oxidative stress, semen, STZ-induced diabetes, antioxidant

Objectives: This study investigated the antidiabetic and antihyperlipidemic potential of the ethanol extract of the leaves and stem of Cissus gracillis on alloxan monohydrate-induced diabetic albino rats. Methods: Preliminary phytochemical screening and acute toxicity were carried out. Animals were assigned into seven groups of five rats each. Groups A and B were administered 10 mg/kg each of glibenclamide and atorvastatin respectively, C, D, and E were given 125, 250 and 500 mg/kg of ethanol extract of C. gracillis, respectively, daily for 21 days through oral gavage, group F was diabetic but untreated (diabetic control group), while group G was non-diabetic and untreated which served as the control group. Results: Phytochemical screening revealed the presence of steroids/triterpenoids and carbohydrates. LD50 was above 5000 mg/kg. The extract at 500 mg/kg showed a statistically significant (p<0.05) decrease in blood glucose level when compared with the glibenclamide group on day 21. However, gradual non- significant reduction in blood glucose levels were observed in the extract treated groups on the 7th, 14th, and 21st days of treatment. The administration of ethanol extract of C. gracillis to alloxan-induced diabetic rats produced a decrease in total cholesterol, triglycerides, and low-density lipoproteins comparable to glibenclamide and atorvastatin. Conclusion: The ethanol extract of the leaves and stem of C. gracillis possess a mildly significant antidiabetic and antihyperlipidemic activity.

Aim: The present study aimed to elucidate the effects of tramadol on the testicular functions of adult male rats due to the chronic usage of tramadol and the effect of its withdrawal. Method: Adult male albino rats were classified into the following 3 groups: (I) a control administered with normal saline and (II) tramadol-treated rats (40 mg/kg b.w. orally) for 21 successive days; and (III) like the rats in the second group but kept for 4 weeks after the last tramadol dose to study the effect of tramadol withdrawal. At the end of the experimental period, blood was collected and specimens from testis were taken for histopathological, biochemical, and molecular studies. A reverse transcription-polymerized chain reaction after RNA extraction from specimens was detected for the anti-apoptotic and pro-apoptotic genes in testicular tissues. Also, malondialdehyde (MDA) was measured in tissues homogenate and antioxidant enzymes activities were evaluated. Results: The results of this study demonstrated histological changes in testicular tissues in groups II and III compared to the control group, accompanied with increased apoptotic index and proved by increased B-cell lymphoma-2 (Bcl-2) associated-X-protein and caspase-3 expression, whereas anti-apoptotic Bcl-2 markedly decreased. Moreover, in tramadol-abused and -withdrawal groups, the MDA level increased, while the antioxidant enzymes activity decreased and revealed oxidative stress, indicating that tramadol is harmful at the cellular level and can induce apoptotic changes in testicular tissues. The withdrawal effect showed signs of improvement, but it did not return to normal levels. Conclusions: It could be concluded that the administration of tramadol causes abnormalities on testicular tissues associated with oxidative stress, which confirmed the risk of increased oxidative stress on testicular tissues due to tramadol abuse.

Aim: The current study observed the antidiabetic effect of Vasant Kusumakar Ras, an Ayurvedic polyherbal formulation, in alloxan-induced and dexamethasone-induced diabetic rats. Materials and Methods: Alloxan (120 mg/kg, i.p.) and dexamethasone sodium phosphate (5 mg/kg, i.p.) were used to induce diabetes in rats. The oral antidiabetic activity of Vasant Kusumakar Ras was evaluated by single doses of Vasant Kusumakar Ras (400 and 600 mg/kg, p.o.) in albino rats during a 10-day treatment period, with the effect of the Vasant Kusumakar Ras on blood glucose levels and serum lipid parameters measured on 0, 7th, and 11th day. Glibenclamide (5 mg/kg, p.o.) was used as the reference drug. Results: In alloxan-induced diabetic rats, the elevated levels of blood glucose significantly (p < 0.05) decreased after oral administration of Vasant Kusumakar Ras (400 mg/kg and 600 mg/kg), and Glibenclamide (5 mg/kg). When compared to the diabetic control group, treatment with Vasant Kusumakar Ras and Glibenclamide for 10 days reduced total cholesterol (TC) significantly (p < 0.001). Treatment with Vasant Kusumakar Ras and Glibenclamide for 10 days, significantly (p < 0.001) decreased low-density lipoprotein (LDL) level when compared to the diabetic control group. In dexamethasone-induced diabetic rats, all rats given with dexamethasone and Vasant Kusumakar Ras (400 mg/kg and 600 mg/kg) showed a significant (p < 0.05) decrease in the level of blood glucose when compared with diabetic control rats. The rats treated with dexamethasone and Glibenclamide showed a significant (p < 0.05) decrease in blood glucose level when compared to diabetic control rats. When compared to the diabetic control group, treatment with Vasant Kusumakar Ras and Glibenclamide (5 mg/kg) for 10 days reduced TC significantly (p < 0.001). Treatment with Vasant Kusumakar Ras and Glibenclamide for 10 days, significantly (p < 0.001) decreased LDL level when compared to the diabetic control group. Conclusion: Vasant Kusumakar Ras was shown to have significant antidiabetic activity comparable to that of glibenclamide and it also improves the lipid metabolism in both alloxan-induced and dexamethasone-induced diabetic rats.

The aim of this study was to evaluate the attenuating effect of given selenium and/or magnesium on ethanol-induced oxidative stress, disturbances of liver function and cholesterol metabolism. Forty male rats were divided into five groups: C – control, Et – intoxicated with alcohol (15% solution in drinking water), Et + Mg, Et + Se, Et + Mg + Se – intoxicated with alcohol and supplemented with selenium (0.4 mg Se/l water), magnesium (100 mg Mg/l water) and combination of Se and Mg, respectively. The experiment was carried out over the 3 months. The results show that the chronic ingestion of alcohol induces lipid peroxidation and histopathological changes in liver. Supplementation with magnesium only partially alleviates oxidative stress and damages in this tissue. The both selenium alone and combination of magnesium and selenium significantly elevated total antioxidant status (TAS) in serum, activity of glutathione peroxidase and ratio of reduced glutathione to oxidized glutathione (GSH/GSSG) in liver and retarded oxidative stress and histopathological changes in this tissue. Chronic administration of ethanol (alone and with magnesium) resulted in significant decrease in the serum total cholesterol and retardation in the body weight gain in comparison with the control group. In the groups supplemented with selenium and selenium and magnesium simultaneously, concentration of total cholesterol in serum and body gains was similar to the control group. Supplementation of Se or selenium and magnesium simultaneously significantly enhances antioxidant defence and is more effective against alcohol-induced oxidative stress, disturbance of liver function and cholesterol metabolism than the separate use of magnesium.

Since the liver is among the primary organs susceptible to the effects of hyperglycaemia, diabetes mellitus (DM) could be a risk factor for the development and progression of liver damage. In present study, since no side-effects from the herbal medicine have been reported, the effect of silymarin on blood glucose concentration, hepatic histopathological changes and FOXA2 and FOXA3 gene expression, which are key genes in liver regeneration, was investigated. In this fundamental with experimental approach study, 40 male Wistar rats weighing 180-220 g were used. Rats were kept under the standard conditions of temperature of 20-22°C and humidity of 50% and consecutive 12-hour periods of light and darkness. Rats were randomly divided into five different groups (n=8 each), including healthy control rats, diabetic control rats, diabetic rats receiving silymarin (50, 100 and 150 mg/kg). Diabetes was induced by injecting streptozotocin (50 mg/kg B.W., i.p.). For 4 weeks silymarin groups received the drug once every three days through gavage and fasting blood glucose concentration measured once every 10 days. At the end of a month experiment, livers were harvested for hepatic histopathological and FOXA2 and FOXA3 gene expression changes analysis. In the diabetic rats treated with silymarin (50, 100 and 150 mg/kg), by comparison with the diabetic control group (p<0.05), glucose levels decreased significantly. Moreover, FOXA2 and FOXA3 expression in diabetic groups treated with silymarin significantly increased compared to diabetic control group (p<0.05). Hepatic histopathological changes were improved in the treated groups.The present study indicates that silymarin significantly decreased blood glucose concentration and increased the FOXA2 and FOXA3 gene products level. Hence, silymarin is able to improve some of the symptoms associated with diabetes and possesses hepatoprotective effects in streptozotocin-induced diabetic rats.

The present study was carried out to investigate and compare the effect of nicotine alone and in combination with melatonin on some oxidants and antioxidant parameters, histopathological changes and DNA integrity in the liver and kidneys of male rats. For this purpose 75 mature male rats weighing 120-140g were randomly divided into five groups; control group (1% ethanol in saline), nicotine group (rats administrated nicotine at a dose of 0.6mg/kg body weight; BW) and nicotine and melatonin groups (rats administrated the same dose of nicotine plus 1, 5 or 10mg/kg BW melatonin, respectively). Nicotine and ‏ melatonin were injected intraperitoneally daily for 21days. Fasting blood samples were collected from each rat one day after the end of last injection (at 22nd day) and sera were collected for determination of total antioxidant capacity (TAC). Five rats were sacrificed from each group; Liver and kidneys were collected for estimation of oxidative stress parameters (MDA, SOD and GSH), histopathological examination and for estimation of DNA damage. The results revealed that nicotine increased MDA, decreased TAC, SOD and GSH, induced histopathological changes and increased the percentage of DNA damage in the liver and kidneys Melatonin administration with nicotine counteracted the effect of nicotine on previous parameters. The effect of melatonin was dose dependent and the 10mg dose produced the highest protective effect. It is concluded that melatonin can ameliorate the harmful effect of nicotine on the liver and kidneys of male rats.

PurposeThis paper aims to study the anti-diabetes activity of the Kombucha prepared from different snake fruit cultivars.Design/methodology/approachThe juices of snake fruits of Suwaru, Madura, Pondoh and Bali cultivars were fermented for 14 days. Anti-diabetes activity of the products was analyzed. Twenty-four male albino Wistar rats were used and randomly divided into six experimental groups, i.e. four groups of the diabetic rats treated with the Kombucha, plus the normal group and diabetic control group. The Kombucha were orally administered to the streptozotocin induced-diabetic rats at 5 mL/kg body weight per day during the 28-day experiment. The fasting plasma glucose (FPG), oxidative stress indices (superoxide dismutase [SOD] activity and Malondialdehyde [MDA] level) and lipid profile of the blood plasma were measured. The pancreas was used for immunohistochemical study and β-cells quantification. Data were analysed by ANOVA followed by Fisher test using Minitab version 16.0.FindingsFPG of the diabetic rats treated with the Kombucha (110.3-189.3 mg/dL) was significantly lower (p= 0.000) than the diabetic control group (413.3 mg/dL). Those were in line with the number of pancreatic β-cells of 42.1 in diabetic rats that lower (p= 006) than those in treated the diabetic rats (61.2-73.5). The treated diabetic rats had lower oxidative stress (SOD activity: 20.9-44.6 unit/100 µL withp= 0.000; MDA level: 0.37-0.48 ng/100 µL withp= 0.000) than those in the diabetic rats (SOD activity: 18.7 unit/100µL; MDA level: 0.84 ng/100 µL). The treated diabetic rats also showed better lipid profile than those in the diabetic control rats. There were cultivar differences, and the Suwaru and Madura snake fruit Kombucha demonstrated the most potential for diabetes management.Originality/valueThis is the first study on in vivo anti-diabetes activity of snake fruit Kombucha prepared from different snake fruit cultivars.
